To LU 10710111, t may concern:

Be it known that I, NICHOLAS W. B AEcHLE, l

a citizen of the United States, residingat Cincinnati, in' the county of Hamilton and.v

operation, and my inventionv consists in thek combination and'arrangementof parts here' inafter described-and claimed; Y

tion of a clutch embodying 'myY invention; Fig. 2, a section on line 2 2 of Fig. 1, the pulley not being shown; Fig. 3, a partial eleva-- tion of the inner side of the clutch; Fig. 4, a

top plan view, partially in section; and Fig. 5

A suitable pulley A' 's rotatably-mounted on shaft B and carries an annular frictionliange a.. To shaft B is secured a suitable casing L, the outerpart of which encompasses the liange c; Aloose frictionering D, having lugs.d n'earits ends, is placed within casingI C. with the lugs d projecting radially through a suitable' opening in -the casing," The encompassing surface of casing C -1sturned concentrieallyvwith shaft B, and the ring D'is of such size as to beslightl s rung inwardly when placedin position within the. casing, where the tension 1n t'herlngnornially vholds it out against the casing and givesa uniform clearance from-the-ii'ange a. {Bearing-lugs E are formed-on either side ofthe casing-opening, and shafts F, having'viiattened endsf, bearing on lugs d, mounted there. in. The shafts F are'providedl with shoulders f and the bearings in lugs-.E shaped to correspond, thus preventing longitudinal e movement of the shaft in one direction. The

shoulder is formed a short distance from. the'terinination of the flattened portion of the shaft, thus leavingthe full strength of the larger' end of the shaft to transmit the strain `from the smaller ortion tothe flattened end. Operating-arms are secured tothe ends of shafts F and, bearing against lu s E, prevent movement of the shafts in the ot er direction.

against the innerends of the contact-pieces. Byturning the screws -in or out the distance between the points of Contact, and consequently the throwof the operating-arms, may '-.be increased or diminished. 'Friction-rollers t aremounted in the sides of nose I to roject .from the sides thereof at its widest hub J, having an annular groove. y', adapted to be enga edbythe'usual ron for this ur- In the drawings, Figurel isa vertical sec- -g 'A p g' P vThe 'bearingfaces ofi-the lugs d are at an angle -to'each'othen with theapeX ofthe an.l -gle' toward the hub, and the. angle is suiii# lcientto cause the lbearing-surfaces to rideoutwardly vrelatively to thebearing-faces of fthe operating-shafts F'when the latter are actuated to throw-the ,clutch into engages ment.` By this outward'move'rnent thepart of the ring. immediately opposite the gap is first brought into'contact with the frictionri1n, wh ile the ring ends are held out of contact, so that the initial contact is-at the-point most remote from the point of application'of the power, andthe parts of the ring between the point opposite t e gap and the ga grad` ually close in'as the grip. lincreases',` t usjin-l .surin'gvuniform contact 'throughout the. en

apply thering tothe flange' a.

It willl be seen that'the operative bearingof theflattened shaft ends on lugs d is a line .bearing, and as'the rotation of the shaftcarf 4ries the bearing edge inwardly there is substantially no sliding actionbetween the shaft edge and lug to cause frictionalwear. The.. relative arrangementof the parts is such that (when the arms G h'avenearly reached their limit'v of outward movement the contactpieces H pass onto rollers'i, so that the final 'n'iovementl thereof'is caused by the'rolling The arms G carry adjustable contact-pieces movement of rollers t', thus greatly alleviat- -`In use. when 'irictional 'uncture'uisfdesired v IOO ing the friction at the moment of greatestA strain.V The inward movement of nose I is continued until the' contact-pieces pass4 slightly beyond the plane of greatest \pro jection of the rollers, in which position thel rollers serve to-lock-thenose 'against with;

drawal. Owing to the fact that when the force is applied to the ends of lring Dit is free to adjust itself t-o fiange c in anyy direction and that the nose I also is free to adjust itself angularly, uniform and 'accurate contact is always obtained between. the ring and flange. The capacity for angular movement by nose I will also automatically compensate for any defects in the adjustment of contact-pieces H The flattened ends f of shaft lF are supported by bearings directly behind their lines ofA application to lugs l), so that =no bending strain is introduced in said shafts.

vIt will be noted that this clutch is composed of a very few parts ofsimple construction, which may be readily assembled and takenv apart. A distinct advantage of the construction is that the bearings for shaft F may be made upon a drill-press, which is simpleand. economical of operation.

:In the drawings I have illustrated my invention as applied to an external friction- ,ring;' but it is obvious that the invention ma be applied to an internal friction-ring wit the same advantages.

While I have illustrated and described the preferred vconstruction for carrying my invention into effect, this is capable of modificationewithout departing from the spirit of the invention. I therefore do not wish to be limited to the exact construction set forth; but f What I claim as new, and desire to secure by Letters Patent, is-
